A source node 11 obtains from a destination node 12 quality information on routes 31 and 32 to the node 12, and adaptively changes data distribution ratios for the multiple routes based on the quality information. In general, code is displayed on a display device formatted to indicated historical information andor real-time information. Each transistor set is arranged in a repeating pattern. A plurality of connector contacts are disposed in each of the at least one ports. The visual image of the target is recorded on a storage media for later playback for display by the gunner at the observation unit or optionally by a commander at a separate commander observation unit. The method of volume rendering comprises obtaining volumetric data represented as a plurality of voxels, sampling the voxels at different resolutions corresponding to the limited number of two-dimensional elements per sample, and compositing the two-dimensional elements in order to calculate values to be assigned to respective pixels for visualization.
